Question for highlander. Do you know if Ivomectin is the trade name for the MSD(merck sharpe and dohme) drug abamectic used to kill ticks etc?
You're sort of right but:
Ivermectin is one compound in the avermectin group (the other being doramectin, trade = dectomax). Trade names include Ivomec which is marketed by Merial that used to be MSD.
The abermectins are part of a larger group of wormers, the macrocyclic lactones. They have little if any activity against ticks (and are lethal to collies as a previous post stated).
Hope this helps. Agree with Apache re ticks, Advantix v good (this from the Search and Rescue dogs, who cover similar ground) always have my doubts about Bob Martin's stuff.
